JACQUARD-CARD-CUTTING MACHINE.

To oZZ whom t may concern Be it known that I, VILLIAM COCHRAN, a citizenof the United States, residing at Paterson, in the county of Passaic andState of New Jersey, have invented certain new and useful Improvementsin Jacquard-Card- Cut-ting Machines, of which the following is aspecification.

T his invention relates to the art of repeating the patterns or designsrepresented by punched acquard cards. The repeating 0peration as nowpractised results in the repeated cards being so far exact replicas ofthe master cards that if there are, for instance, sixty-four rows ofunits (perforations and blanks) in the. length of the master card, eachrow having a length of ten units, the repeated card has also sixty-fourrows, each of ten units. Quite often the fabric manufacturer finds itexpedient or necessary to put into operation jacquard machines adaptedfor cards of one size (or punched field or area) punched with the samedesign or pattern as is or is to be worked out in cards of a differentsize capable of being used only in other jacquard machines. But this canonly be done by having the design first worked ont in a piano machine incards of the desired or new punched field or areaan operation which istedious, slow and expensive and requires more or less highly skilledlabor-and then repeated, using the cards thus produced as master cardsin a repeating machine operating as above indicated.

rlhe object of this invention, therefore, is to provide a machinewhereby the repeating operation may be performed under conditions wherethe repeated cards are to have any punched field or area, that is,either of the same width as, or wider or narrower than, the punchedfield or area of the master card or other piece.

in the accompanyingI drawings, I have illustrated my invention by way ofexample in the preferred embodiment thereof, Figure l being a frontelevation of the machine, with certain parts broken away; Fig. 2 a sideelevation thereof, partly in section; Fig. 3 is a fragmentari,7 sideelevation, on a larger scale, showing the head in which are housed thepunches and their abutment keys and also showing the card feeding means;Figs. fl and 5 show a fragment of the said head, a

few of the punches and their abutment keys with the head depressed andall of said punches operative in the one instance (Fig. 4) and only apart of them operative in the other instance (Fig. 5), Fig. i alsoshowing a part of the means which controls the abutment keys; Fig. 6shows several of the punches and. in section in a vertical plane on acrosswise line of the punches, certain parts in which the punches areguided; and Figs. 7 and 8 are plan views of a master strip or piecehaving the design to be repeated and a blank card undergoing therepeating operation, certain punch guides 0 and g being als-o shown inplan.

The frame a has a bed Z on which are arranged the adjustable guides cfor the blanks A, which are to become the repeated cards. rlhe blanks Aare fed enclwise over the bed Z) from front to rear by the clip CZ shownin Fig. 3, said clip being a part of a traveler e which is normallydrawn rearwardly by a weight /f connected with the traveler by a cord orthe like g extending over a pulley 7L arranged at the rear end of ahorizontal guideway on which the traveler slides. .fin escapementmechanism, forming no part of this invention and which it is unnecessaryto describe further than by indicating the part j to be a fixed rack,and 7c two pawls which coperate with the rack and move with thetraveler, receiving' an oscillating motion from the rock shaft Z whichis actuated through the connecting means m from the main rotary shaft n,is employed, the same causing the rearward movement of the traveler, andhence of the blank card A., to be a step-by-step one.

On the bed b is arranged a guide o for the punches, the same beingperforated for the reception of the punches, which is of course truealso of the bed Z) which thus forms a die. The head, y), includes the pa't f7, for the reception of the punches, and the harped-shaped structure1' whose inclined portion s is stepped on its under side as shown andhas a series of horizontal apertures fo 1ming guideways coinciding withthe steps of said portion s. The punches Z1 are ar v'anged in thepresent instance in five crosswise rows or lines, there being sixteenpunches in a row. The part g of the head has five cross-wise sl-ots il,formed with shoulders o and receiving the rows of punches whose fixedcollars w are held against the shoulders lv by spiral springs interposedbetween part Q and Collars y on the punches. rThe punches t areoperative in working out the design; other punches t yieldinglysupported in substantially the same way as the punches t may serve f-orforming the holes in the cards whereby the latter are laced together.The head j) is carried by two uprights a which slide in the bed b andbrackets 2 and are rigidly connected by the crosshead 3 which isreciprocated from a crank 4; on the shaft a, by a pitman 5.

The apertures in the inclined or stepped portion s of the head j) arearranged in five rows of sixteen apertures to a row. In them slide theabutment keys 6, of which there is one for every punch t. The punches tare graduated in length (F ig. 1) and each is of such length that whenits corresponding abutment key G overhangs the punch, being at that timemoved inward to a limit afforded by a stop 7 on the key, the punch willbe active, but when the key is withdrawn as shown in Fig. 5, the punchmay recede on impact with the card being punched. This part of themachine is old and well-known. -Each abutment 6 has an extension Spivoted thereto and in the pres-- ent instance consisting of a wire. Theseveral wires are guided in the grids 9 of a frame 10 which is securedto the side of the frame a, the openings in the grids for the receptionof the wires being vertical slots 11. The portions of the wires whichare received in the grids are horizontal, while the portions thereofbetween the grids and the abutment keys are inclined downwardly, thatis, by bending the wires; this results in the parts 6 and 8 being heldagainst turning, preserving certain bends 12 in the wires, which formstops to engage the extreme lefthand grid, always projecting upwardly.Springs 13, interposed between the extreme right-hand grid and fixedcollars 1-/1 on the wires 8 normally press the latter to the left in thedrawings. Thus, as the head rises and falls, the abut-ment keys arenormally held by the springs 13 at their inward limits of movement, thatis, overhanging the punches.

The rendering of any punch inactive is accomplished by raising itsextension 8, when the head is at its highest elevation, until the stop12 is in position to be opposed by the left-hand grid 9 againstlongitudinal left-hand movement; the extension being thus held againstlongitudinal movement, when the head descends the result will be towithdraw the abutment key out of overhanging relation te the punch. Toaccomplish the selective raising of the extensions I provide thcvertical needles 15 each formed with an eye 16 loosely receiving one ofthe extensions. The needles 15 are guided in the grids 17 of the frame10, being held by gravity with their collars 18 resting on the lowergrid 17. `The needles are arranged in the presentI instance tenin-a-rowin eight crosswise rows.

19 is a vertically movable carrier having an arm 20 which penetrates andis suitably guided by a slot 21 in the side of the frame 0, and has asleeve 22 loosely embracing one of the uprights .2. By means of a pitman23 the carrier is connected with a lever 24 which rests on a cam 25 onthe shaft n, the carrier being supported by the cam through the mediumof the parts 23 and 241. The carrier has a perforated horizontal needleboard 26 the holes in which correspond in number and disposition to theneedles. rl`he master strip B which is punched with the pattern ordesign to be repeated, is fed over the needle board from the supply drum27, journaled in the carrier and having a crank 28, to a take-up roller29, also journaled in the carrier. To keep the strip B under tension,the drum 27 may be suitably adapted to offer resistance against rotationand the take-up roller may be influenced by a weight 30 to tend torotate in the direction of the arrow in Fig. 2. The weight 30 isattached to one end of a cord 31 which is wound on a drum 82 pressedagainst the end of the take-up roller by a spring 83, the abutting facesof the drum 32 and take-up roller being formed as ratchet clutch members34, as shown in Fig. 1. By this arrangement, when the weight hasdescended until the cord has nearly or quite unwound, the drum 82 may bererotated independently of the take-up roller so as to rewind the cord.

35 is a guiding roller for the strip B arranged forward of the needleboard. The strip B is formed with two lateral rows of perforations 36(it being'understood that the other' perforations between these rows 36constitute the design) with which engage the peripheral studs on a drum37 revoluble in the carrier below the needle board and provided with aratchet 3S. lWith this ratchet engages a pawl 39 which, on each rotationof shaft n, is actuated from a cam l() on said shaft through the mediumof a lever l1.

42 is a perforated plate receiving the needles 15 and carried by theuprights 43 at such an elevation above the collars 18 on the needlesthat each time the carrier descends it will engage said collars andinsure the return of the needles to their lower most positions.

Operation: On each downwardl stroke of the head j) the cam 4:0 engagesthe lever 41 and causes pawl 39 to advance the master strip B therequired distance to bring the part of the design or pattern immediatelyfollowing that last iniiuencing the needles under the latter, thisoccurring when (lever 2st being now depressed) the carrier is down andthe strip B is thus clear of all oi2 the needles. During the descent ot'the head p the plate 42 acts to reset such needles as were last raisedin the selecting operation. Those punches which are backed by abutmentkeys of course operate at this time to perterate the card A, the restyielding upwardly in the head p. On the rise of the head the tollowingoperations occur: The escapement mechanism shown in Fig. 8 produces thenecessaryincrement of advance of the card A so as to bring it intoposition tor the n xt punching operation. The cam 25 causes lever' Q4:to act through pitman 28 to raise the carrier. Strip B, now advanced tothe new position, thus effects the raising et certain of the needles,.leaving the rest unclevated, the raising ot' the extensions Sappertaining to the needles thus raised bringing the stops of saidextensions to the position indicated by the dotted outline in Fig. il.On the now-ensuing downward movement ot the head the abutment devices 6,8 Whose extension portions 8 are raised cannot move longitudinally orthrustwise relatively to fra-me 10 under the pressure of the springs 13owing to their stops engaging the left hand grid in Fig, et, so that assoon as the head descends they perform a (retreating) thrust-movementrelatively to the head out of abutment relation to the punches; the restpartalf'on the other' hand of thrust-movement relatively to trame 10 as,held by their springs to the lett, their abutment-key-portions descendwith the head. T he cam 25 is so formed that it holds the carrier, whenelevated, in a state of dwell of sutlicient extent to maintain thelocked-back condition of the called key-abutm-ents until their puncheshave, by engaging the card, been pushed sufliciently upward in the headto prevent said abutment keys trom slipping over them.

It will be understood that the relation et' the selecting needles to thepunches is variable, the order in which the needles are coupled with theextensions S being not lixed but capable of change by changingabout theneedle-eyes 16 with respect to the extensions or the abutment keys intheir' apertures, so that the machine may be adapted to master stripsand cards to be punched whose punched lields or areas may vary. In thepresent instance, as stated there are 8 crosswise rows of selectingneedles, 10 to a row, making 80 in all; there are 5 rows oit' punches,16 to a row-80 in all. Counting from rear to front as to rows and fromright to left in each row, the first punch is coordinated with the iirstneedle, and so on throughout the two groups (punches and needles), asindicated by the numbers 1, 11, 21 etc. on the strip and card shown inFigs. and 8 and on the punches in Fig. 8. The groups ot units separatedby transverse dotand-dash lines in Fig. S and indicated by Romannumerals correspond to the groups of units similarly designated in Fig.7.

it will be understood that by following this method of arranging thepunches with reference to the selecting devices the extent of each rowof punches may be varied as desired so as te change the width-gage ofthe repeated card, although the width-gage et the master strip remainconstant; itbeing always necessary, however, that the last unit (numb-er8O in the present instance) of the repeated card occur at relatively thesame side thereotl as the last unit appears in the master strip. Themethod above indicated l have made the subject of my application iledMay 15, 1912, Serial No. 697,439 and is not claimed herein.

ln the repeating operation it may frequently be desired or necessary torepeat either a series of designor pattern-sections Il, lll, etc., orany one of them. ln such case, the strip B can be fed backward thedesired distance by rerotating the supply drum 27 by means et handle QS.
